To determine if 8402 is a prime number or a composite number, we simply look at the factors for 8402.
If the factors of 8402 are only 8402 and 1, then we know that 8402 is a prime number. Otherwise, 8402 is a composite number.
To explain better, if 8402 is only divisible by 1 and 8402, then it is a prime number, and if 8402 is divisible by more than 8402 and 1, then it is a composite number.
The factors of 8402 are as follows:
1, 2, 4201, 8402
Therefore, since 8402 is divisible by more than one and itself, the answer to the
question "Is 8402 prime or composite?" is highlighted in blue below.
